Timeline

Traffic Impact on Coral Ridge Avenue

There will be traffic delays

One lane of traffic will be maintained in each direction on Coral Ridge Avenue through the project corridor

Detour, approximately mid-May through mid-November: Coral Ridge Avenue traffic will detour using Oakdale Boulevard, Crosspark Road, and Wheaton Road to give the contractor full access to this section of the roadway. While it is inconvenient, this temporary closure will speed up the overall project timeline.

Pre-Project Planning

Duct Banks

In anticipation of the project, underground duct banks were proactively constructed in 2017. These duct banks provided places for the private utilities companies to relocate their overhead and underground facilities to be out of the way before the 2018 improvement projects. The duct banks should minimize delays caused by private utility relocations, which can be common during street projects.
